For the given reaction :
What is 'A'?
What is 'A'?
Show Hint
- \(\mathrm{CH_3CH_2CH_2NH_2}\)
The Correct Option is A
Solution and Explanation
Step 1: NaNH2 (strong base) removes HBr (dehydrohalogenation) to give propyne, CH3-C\(\equiv\)CH.
Step 2: alkynes undergo cyclic polymerisation when passed through a red hot iron tube at 873 K. Three molecules of propyne give 1,3,5-trimethylbenzene (mesitylene).
Option (2) is benzene (from ethyne), option (3) is an enamine and (4) is propylamine, neither of which can form.
Answer: (1) 1,3,5-trimethylbenzene

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
